Hey guys.. I have a problem with my Pioneer DEH-P550MP cd player that I hope you can help me with. The cd player will not turn on when wired up, unless I wire the yellow igniton wire and the red power wire together in the same connection. However, this causes the cd player to have no memory and I must reset everything every time I turn off the car. Anyone know why this might be?? It's really annoying having to reset all settings four or five times a day.

Get a voltohmmeter and check if theres any power through each of the power wires, if there isn't, thats your problem, if there is its the HU. Also when checking the actual +12v wire that will only work when the car is on, but the memory should be on all the time.
your fuse is blown. this happened to me as well. replace the blown fuse and it will work fine correctly wired.
have a nice day.
you should also notice that some other electronic items in your car have most likely gone haywire. (dome lights\odometer ect) this will fix them as well.
what type of car do you have and where did you get the wiring kit?
